3. INTRODUCTIONINTRODUCTION
 This project is designed with ARM7TDMI
processor.
 The project is implemented by using two
modules
Base station module
In-Bus module

4. Block Diagram: In-Bus Module

5. WORKINGWORKING
 This project contains two embedded system
modules one will placed inside the bus and the
other will be placed at the bus stops.
 The location of bus can be find out using GPS
and can be sent to bus stop using GSM.
